The hardmasking of gnome 3.8 was removed a few hours ago and those using gnome 3.6 in ~arch will be asked to upgrade to gnome 3.8/systemd in their next upgrade world. If you want to stay with 3.6 for the time being, here you will find the list of packages that the gnome 3.8 hard mask used to contain.

And what if I wanted to do the update, How do I switch from udev to systemd and what else is necessary because I saw alot of blockers (udev and systemd being just part of the problem)_________________Billy DeVincentis

Not a Gnome user but I'd assume you need to unmerge udev and consolekit (may need to emerge -C them), emerge systemd after make sure you have the "systemd -consolekit" flags set and be sure to follow the Gentoo doc and wiki on systemd to make sure you get it set up right.

Post the output with the blockers anyway, someone can probably point you in the right direction

I'm in the process to update do G_3.8 as well.
Systemd is running, basic services run out of the box with the notably exception of lan. I had to manually set 'systemctl enable dhcpcd'
I did not manage to start apache2, nfs and samba correctly yet.

From a strikt user perspective, systemd is faster than openrc during the boot-process.

Don't expect to run a full-fleged multi-service system without a considerable amount of extra-work!

I did the systemd migration awhile ago. IMHO its better than OpenRC and Upstart.

However I was very interested in trying gnome-3.8. I like it but it seems a little buggy.

1. In gnome3-classic you get the menu and the mouse action when you goto the top left of the screen. Every once and awhile both of those just stop working. Meaning I can't start new apps unless I have a terminal up.
2. I just went to play Heroes of Newerth(a native Linux OpenGL game) and it was really really painfully slow.
3. It broken cinnamon! But thats probably fixed in a newer version of cinnamon.

I noticed that despite these being new ebuilds there is an even newer version of gnome out, 3.8.3. Any reason the newer versions weren't used? I'm hoping these bugs are fixed in the newer upstream versions.

I did the systemd migration and move to Gnome 3.8 in one go last night, but now I have a problem: when I lock the screen and then try to unlock it again I get an "Authentication error" message on the password screen (before typing in my password) and afterwards I get a throbber and no further response. I can log in (with password) with GDM at the beginning of the session, though. Does anyone else have this problem?

The first one looks to me like a bug, please be sure you are running latest packages and report a bug in bugs.gentoo.org showing exact steps to reproduce (I will probably ask you to also report to upstream -> bugzilla.gnome.org after that )

Regarding the second one, I can run games properly, I would google a bit and search for problems with that specific game :/, if nothing is found, feel free to report and we can try to see what to do.

The third one is being handled in https://bugs.gentoo.org/show_bug.cgi?id=470248 but, as nobody in gnome team is really caring of cinnamon, it is a bit stalled. I have done some comments at the end of that bug to try to cleanup things a bit, if you can offer some help there, that would be nice

Updating to Gnome 3.8 succeeded as well here.
However, I have an issue. I can't log in a newly added users. Screen remains grey (gdm-background) after logging in, and bumping the upleft corner with the mousepointer makes my whole screen flickering nasty.

Logging in into other accounts is an adventurous task, as the shell might not come up correctly. Once I'm succesfully logged in I have not found any nasties yet.

I have kde-4.10.5 and 4.11 is not in the tree yet; I was hoping not to have to use an overlay tree

Anyway I would appreciate some help with the migration since the multitude of portage messages confuses me and I am stuck in the trial-and-error approach. here is my portage output (sorry for the long list)

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.
